About 1.3 billion light-years away, two massive black holes had merged, and the resulting shockwave—a gravitational wave—was strong enough for LIGO to detect the moment it washed over Earth. Since ...

Last November, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, picked up something odd. An automated alert ...

After a prolonged absence from the gravitational-wave-detection scene, the massive LIGO project is back up and running. The Laser Interferometer Gravitational-Wave Observatory (LIGO) works in ...

The LIGO observatory near Richland has detected the apparent gravitational ripples from a black hole swallowing a neutron star. It could be a scientific first. Just after 2 p.m. Aug. 14, the Hanford ...

A strange gravitational-wave signal detected by LIGO has reignited interest in one of cosmology’s most persistent theories.

RICHLAND – The renowned experimental physicist and Nobel laureate whose brainchild resulted in the LIGO observatory at Hanford in Eastern Washington has died. Rainer Weiss, 92, died Aug. 25 in ...

Three years ago, a little-known telescope made waves with an incredible discovery, or rather, detected some waves. In 2015, the LIGO telescope became the first to detect gravitational waves, first ...

The Nobel Prize-winning project that hunts for gravitational waves— ripples in space and time—is about to begin the longest and most sensitive observational run to date. The National Science ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Since 2020, the ...

One of the most remarkable experiments in history — a pair of giant machines that listen for ripples in spacetime called gravitational waves — will wake up from a half-year nap on Monday. And it will ...
